Segement Test on ATLAS ITk Strips End Cap — •Konstantin Mauer — Deutsches Elektronen-Synchrotron DESY, Hamburg

The upcoming High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) will significantly increase its instantaneous luminosity. This will lead to a higher track density, a higher hit rate and an increased amount of radiation damage in the experiments. For this reason, the ATLAS experiment will be upgraded, and a new all-silicon inner tracking (ITk) detector has been designed, consisting of strip and pixel detector modules.

In the outer layers silicon strips modules are used and loaded onto local support structures. In the forward directions these are called petals. They are integrated into an End Cap (EC) mechanical structure at one of the two EC integration sites. After welding 16 petals to a cooling manifold, this segment will be fully powered and characterized using the final detector powering chain and readout devices.

With the production ramping up, petals are accumulating for fully populating the first segment. Thus, in summer 2026 the first segment test is scheduled. This talk presents ongoing preparations towards this milestone.
